TYPE-WRITING MACHINE.

Patented Mar. 26, 1912.

To all whom it may concern:

Be it known that I, JACOB FELBEL, cit-izen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certaln new and useful Improvements in Type-Writ1ng Machines, of which the following is a specification.

My invention relates to typewriting machines and. more particularly to type actions.

The main object of the invention, generally stated, is to provide an eificient type action for a visible or front-strike machine and one in which lateral or side strain is avoided and a uniform or substantially uniform leverage and dip of the keys is provided throughout the system.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices to be set forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure l is a fragmentary vertical central, fore and aft sectional view of one form of typewriting machine embodying my invention; only so much of the machine being shown as is necessary to illustrate my invention. Fig. 2 is a vertical, transverse, sectional view of the same taken on the line ww of Fig. 1 and looking in the direction of the arrow atsaid line. Fig. 3 is a fragmentary, horizontal, sectional View of the same taken on the line 00-00 of Fig. 1 and looking in the direction of the arrow at said line. Fig. 4 is a view corresponding to Fig. 1 but showing a modified form of construction. Fig. 5 is a transverse, vertical, sectional view of the same taken on the line y3 of Fig. 4 and looking in the direction of the arrow at said line. Fig. 6 is a fragmentary, horizontal, sectional view of the parts represented in Fig. 4; the section being taken on the line 2-2 of Fig. 4 and looking in the direction of the arrow at said line.

Referring first more particularly to Figs. 1, 2 and 3 of the drawings, the frame of the machine comprises a base 1, corner posts 2 and a top plate 3. A platen 4, diagrammatically represented in the present instance, is mounted in a carriage and supported in the usual manner for movement across the top plate from side to side of the machine. A segmentally arranged series of type bars 5 are pivoted at 6 to move upwardly and rearwardly and strike against the front face of the platen 1. The type bars may be mounted in any suitable manner but in the present instance are shown received in guide slots 7 in a vertically disposed type bar segment 8, and are mounted to turn on the pivot wire 6. Each type bar is connected as at 9 to one end of a contractile returning spring 10, the opposite end of which is connected at 11 to the type bar segment. Supporting rods 12 extend forwardly from the type bar segment and support a segmental strip 13 on which a type bar rest or pad 14: is mounted. The type bar segment in the present instance is mounted for vertical case-shift movement and is preferably provided with grooved guide ways in its sides v15 for the reception of anti-friction balls or rollers 16, which are likewise received in corresponding grooved guides 17 provided in upwardly extending bracket arms 18, secured to the frame of the machine. The type bar segment is thus mounted for vertical case shifting movement under control of a suitable'key or keys not shown. To each type bar is pivoted at 19 a rearwardly extending pull link 20 which in turn is pivoted at its rear end, as at 21, to the upper end of an upstanding sub-lever 22 of the first order. Each sub-lever 22 is pivoted at 28 to a hanger 24 arranged in a slot 25 in a seg ment 26. A screw 27 is cooperative with each hanger to hold it in place; each screw entering a tapped opening 28 in the side walls of a slot 25 in which a hanger is mounted. The various slots 25 are vertically'disposed, are in parallel arrangement and are segmentally arranged, as indicated in Fig. 2, so as to provide for a corresponding arrangement of the sub-levers 22 at the pivot-s and at the upper and lower ends thereof; it being understood that the sublevers are of uniform size or length. From an inspection of Fig. 2 it will be observed that the upper ends of the sub-levers 22 are arranged in an are which corresponds substantially to the arc in which the segmentally arranged type bars are disposed, so that a direct fore and aft movement may be transmitted from each sub-lever 22 to the associated type bar 5, through the intermediate pull link 20. The lower arm of each sub-lever 22 is preferably slightly inclined rearwardly to provide an inclined face 29 for cooperation with an anti-friction roller 30 mounted on a pivot pin 31, atthe inner end of a substantially horizontally disposed sub-lever 32 of the third order; the sub-lever 32 being pivoted at 33 on one side of a hanger arm 34. Each of the hangers 34 is mounted in a vertically disposed slot 35 in a segment 36, which latter is secured to the base of the machine in any suitable way. A screw 37 is provided for each hanger, each of said screws being received in an opening 38 tapped in the side walls of each slot 35. The sub-levers 32 are parallel, segmentally arranged, and are of a uniform size or length. The width of the series of sub-levers 32 is substantially the same as the width of the series of sub-levers 22 and the series of type bars 5 and the upwardly opening arcs in which the type bars and the two series of sub-levers are pivoted are in parallel arrangement. A depending pull link 39 is pivoted at 40 to each sublever 32 and is likewise pivoted as at 41, to a key lever 42 of the second order, which is substantially parallel with the associated sub-lever. The key levers have a fanning arrangement and they are all pivoted on a pivot rod or wire 43 supported in the base of the machine. The key levers extend forwardly beneath the sub-levers and are provided with the usual finger keys 44 and with returning springs 45.

From the foregoing description it will be understood that each of the series of substantially, horizontally disposed sub-levers 32 directly cooperates with the associated sub-lever 22,in the sense that there are no intermediate actuating connections such as sub-levers or links between the two co-acting sub -levers, although an antifriction roller is preferably employed to reduce the frictional engagement between the co-acting. sub-levers. Moreover, it will be understood that the pivotal centers of the sub-levers 22 and 32 of both series are arranged in arcs; that bot-h series of sub-levers are arranged in the rear of the type bars; and that each sub-lever of one series is arranged at an angle to its cooperative sub-lever of the other series; that one of the two cooperative sublevers has an inclined portion with which the other sub-lever co-acts during the depression of a finger key to effect an operation of the type bar. It will also be seen from an inspection of Fig. 2 that the sublevers 22 and 32 are both arranged at gradu ally increasing elevations from the center to the sides of the system, and that the pull links 39 are of gradually increasing lengths from the center to the sides of the system to compensate for the variation in elevation of the sub-levers with which the links 39 are connected. It will be understood that the leverage and extent of dip of the keys throughout the system is uniform, except for the slight variation that may be provided by reason of the different lengths of key levers.

From an inspection of Fig. 3 it will be seen that the key levers 42 are fanned or inclined rearwardly and inwardly from the sides of the system; and that the vertically disposed links 39 are directed downwardly in straight lines from the sub-levers 32 to which they are connected to the key levers 42 to which they make connection at the inclined portions of the key levers. By reason of this construction a direct downward pull on each link 39 is transmitted to the associ ated sub-lever 32 which receives an up and down movement, and that this movement is transmitted in the same plane with the associated sub-lever 22 which, however, receives its vibratory movement fore and aft of the machine to transmit movement to the type bar. A single vertical fore and aft plane therefor will cut or substantially cut, the point of connection 41 between the key lever and its link and between the other actuating connections intermediate this point of connection and the point 19 where connection is made with the type bar so that there is no side strain or pull on the parts but they move easily and effectively during the depression of a finger key. In other words, each individual type bar action from type to key lies in or substantially in a vertical plane considered lengthwise of the machine. Moreover, the construction is such as to afford a vertical case shift movement of the type bar segment without affecting the operativeness of the actuating connections.

In Figs. 4, 5 and 6 I have shown a modified form of construction which will be readily understood from the foregoing description of the construction illustrated in Figs. 1, 2 and 3. In the modified form of construction I have employed the same reference numerals to designate parts which correspond to those embodied in the previously described construction with the addition thereto of the exponent a although parts which are identical in the two constructions bear the same reference numerals. It will be seen that in the modification the sub-levers 32 are more inclined than they previously described construction to afford a camming action of one sub lever on the other. Otherwise the parts are constructed and arranged substantially the same as in Figs. 1, 2 and 3.

Various changes may be made without departing from the spirit and scope of my invention.
